[PATCH v4 00/24] mtd: spinand: driver improvements

[Mikhail Kshevetskiy]

This patch series makes u-boot spinand driver almost the same as spinand
driver from linux-6.17-rc1. This provides the following improvements:
 * it becomes easy to port changes from linux kernel
 * more flash is supported
 * spi drivers can accelerate flash reading/writing using spi-mem dirmap API
 * continuous reading mode was supported
 * OTP support was added (for some flashes)
 * add support of special data recovery reading (for some flashes)
 * bug fixes
 * other minor improvements

The following linux kernel driver features was not implemented
 * support of different ECC engines
 * per operation maximum spi bus frequency

The patchset also includes fixes for continuous reading mode.
The similar patches were sent to upstream linux kernel.

Changes v2:
 * update patch description
 * add fixes for continuous reading mode

Changes v3:
 * fix duplication in patch description
 * add more information about commits ported from linux kernel

Changes v4:
 * the original authorship was preserved for several patches
 * the code was synced with the latest shapshot of future linux-6.17-rc1
 * spi-nand was replaced by spinand in patch description
 * continuous reading mode fixes were updated
